as well as more durable and stronger than my former device.

Another object is to provide means whereby the storm window is normally locked against movement while the window sash proper is fully closed, or even partially so within the limits of the vertical movement so thereof without automatically opening the storm sash.

Still another object is to provide means whereby when the window sash proper to which the storm sash is attached is fully closed the biasing of the storm sash in its closed position is materially augmented.

Other objects and advantages of the invention will appear in the following description thereof. 3 Referring now to the accompanying drawing, forming part of this application, and wherein like reference characters indicate like parts:

Figure 1 is a perspective view of a fragmental portion of a storm sash and window frame illustrating their open cooperative relation with the improved fastener attached.

Figure 2 is an elevation of the fastener bracket as viewed axially towards the pivot of the sash arm when applied thereto.

Figure 3 is a perspective view of the bracket engaging end of the fastener arm.

1 represents a portion of the sideof a window frame, the parting strip being shown at 2, and in Figure 1 the lowermost sash of the window is illustrated at 8. 4; and 5 represent the right angularly disposed walls of the angle bracket which isattached to the outer face of the sash 3 as by suitable screws not shown through theelongated slots 6 in 1929. serial no, 352,420.

the wall 1 of the angle bracket. Intermediate of these elongatedslots is struck from the wall 4 the flange like wall 7 extending outwardly parallel with the wall. 5, and spaced'therefrom a suitable distance to allow free vertical reciprocation between them of the semi-circularlyshaped terminus 8 of the innermost end 9 of the sash fastener arm; it notlbeing considered necessary to show more of the fastenerarm for the description of my present inventionyit being well' understood that the outer end thereof is pivotally attached to the storm sash. Onthe innermost terminus 8 of the sash armis securely fixed the pintle 10 which acts as a pivotal 5 support forcthe innermost end ofthe arm and is operable vertically within the 1 elongated slot 11 formed-substantially the entire length of the wall 5 of the angle-bracket. An arcuate throat like cutout portion 12 7 is formed in the end of the arm, bifurcating same, andjproviding the rectangularly shaped terminus 13, the end ofwhich is turned at right angles to the body portion forming the lip 14; extending parallel withthepintle 10; and, forengagement within the throat 12, thelower extremity of the wall 5 is bent at right anglesthereto and arcuate in shape forming theshoe like lip 15, the functioning of which is similar to thepintle 21 in my above identified copending application, though as is obvious having the advantage of a muchgreater area with the lower wall of the throat 12. i i 1 Upon the lower extremity of thewall 4 of 35 the angle bracketis formed the lip 16 which is shorter than. the full width of the wall 4 providing a receptive space for the terminus 13 of the bracket arm, and this terminusas before stated being formed with the lip 14- will abutgdirectly;againstthe lower inner corner face of the wall 4: of the angle bracket when the arm is in its substantially parallel position as shown in Figured of the drawings, and which position limits the opening of the windowand storm sash. However it is obvious that when the window sash 3 is lowered andthe storm sash moves to closed positionthe outer end of the arm will move towardsla positionparallel with the walls of Mel;

this point be readilydisconnected by movement thereof axially of the pintlelO, and

which point is designated for convenience 7 V of observation by the notch 18 in the back of the arm. r

As the closing operationof the windows is continued with the members'assembled asshown, it is apparentjthat the inner end of V the arm quicklypasses that point at which it may be disconnected, as the semi-circular end 8 enters thechannel intermediate ofthe flange 7 and wall 5, and as the storm sash 'comes'to closed position the lip Men the terminal 13 of the arm will commence vertical movement along the outermost edge of the wall as the window sash'is lowered, it of coursebeing; possible of lowering beyond dow sash including means whereby a predetermined movement of the Window sash may occur without moving the storm sash, of

means whereby during said predetermined movement ofthe window sash the storm sash is locked against independent movement to finalclosed position. a a. y y

this point until the pintle 10 has-reached the l upper extremity of the slot 11 in the wall '5 7 without affecting the outer sash until "the lip 14 reaches the hump 17 upon said outer edge I of the-wall 5 when, immediatelyupon the lip attempting to climb-said hump, additional thrustinwa rdly of the upper end of the arm 9 which is attached to the storm sash occurs as the pintlelO acts as a fulcrum to the leverlike action of the terminal 13 thus engaging the hump.

I claim and desire to secure by LettersPatent,is: $6

cooperatively uniting a storm sash with a lJThe combination with afastener for window sash, of means'formed integral with the fastener whereby final closing positionof the window sash will lock the storms'ash'rig- U idly against movement.

means whereby during said predetermined movement of the window sash the storm sash r a is locked against independent movement. p
